EJ ECTOR FOR REVOLVERS.

SPEGIFIGATION forming part of Letters Patent No; 547,525, dated October8, 1895.

Application filed June 19, 1895- To aZZ whom it may concern.-

Be it known that I, FREDERICK SMITH, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement in Ejectorsfor Revolvers, of which the following, together with the accompanyingdrawings, is a specification sufficiently full, clear, and exact toenable persons skilled in the art to which this invention appertains tomake and use the same.

This invention relates to an improved construction of theejector-actuating devices or means for catching and releasing thehookplate as the barrel is tilted forward, the object being to afford asimple and efficient construction that can be manufactured with economyand practical facility; also to provide a radially-reciprocatingcatch-stud supported within the hook-plate, together with a coiledspring therefor, and adapted for operation in conjunction with thebarrel and frame in the specific manner set forth; also, to combine thecatch-stud and spring devices with the hook-plate in permanentassemblage, thereby obviating liability of displacement or loss when thearm is unjointed for cleaning or repair.

These objects I attain bya mechanism embodying the peculiar constructionshown in the drawings, wherein- Figure 1 is a part side part sectionalview of a revolver embracing my improvement. Fig. 2 is an enlarged sideview of the hookplate and stud. Fig. 3 is a section transverse of thesame, and Fig. 4 shows details of the stud separate from the hook.

Referring to parts, A denotes the frame of the revolver; B, the barrel,hinged to the foreend of the frame at Pto tilt forward in usual manner;C, the cylinder, mounted on the nonrotatable tubular spindle D; and E,the ejector, having the stem E and return-spring e, all of which partsmay be of suitable or wellknown construction.

F indicates the hook-plate, arranged in the center of the hinge betweenthe barrel-ears and pivoted on the hinge-pivot P, said plate having theusual integral hook f projecting from its periphery for engaging the endof Serial No. 553,263- (No model.)

the ejector-stem E. In accordance with my invention this hook-plate isformed with a rectangular notch or recess 2, extending across itsperiphery at the position shown, the upper and lower ends of said recessterminating with parallel shoulders 3 and 4, while the bottom of therecess is preferably straight and square between said shoulders. Aradiallydisposed hole 5 is drilled from the bottom of the recess towardthe center axis. this recess I arrange a square-headed stud I, havingashank 6, that enters the hole 5, while the head of the stud fits therecess 2 and fills the space between the parallel shoulders 3 and 4closely, but ina manner to move freely therein. The width of the head isof the same dimension as the thickness of the plate. Sufficient space isprovided in the recess beneath the head of the stud to allow itsmovement for retracting the head wholly within the limit of theperipheral circle of the hookplate, and an expanding spiral spring J isarranged in the inner part of the hole 5, which spring acts against thestud and normally presses it outward, the stud being thus adapted forreciprocal movement in a direction radial to the circle of thehook-plate. One side of the shank 6 is cut away, as at 7, for a suitablespace, and the stud is retained in the hook-plate and limited in itsmovement by a small retaining-pin 8, that passes through the hook-plateand engages the cut-out space 7, as indicated. The outer end of the studis fitted with an incline or outwardly-curved cam-surface 9, whichnormally stands at the shoulder 3, flush with the peripheral surface ofthe hook-plate and terminating near the opposite part of the head in anarrow surface 10, formed flat or concentric with the circle of thehinge-ears. At the lower part of the head the stud normally projectsbeyond the peripheral circle and presents an edge or shoulder m forcatching upon the shouldera at the fore-end of the frame.

In the operation when the barrel is un- 5 it to force outward theejector E (see dotted 10:

Within 60 line, Fig. 1) as thebarrel is further tilted. Then theshoulder 19 of the barrel approaches the end of the frame, said shoulderacts against the incline or cam-surface 9 and, in opposition to thespring J, forces the'stud inward until its end 10 is brought Within theperipheral circle or so that it can pass Within the hinge-chamber at thebottom of the frame, thus disengaging its edge 1% from the shoulder aand releasing the hook-plate F and its hookf. Then the ejector isimmediately returned to its normal position by the force of the ejectorreturn-spring e in well-known manner. l/Vhen the barrel is tilted backto its normal position and the stud I swings outward past the end frame,the stud is reciprocated to its normal position by the coiled spring J,acting against the inner end of its shank 6. If it is desired to dropthe ejector before the full tilting of the barrel, it can be done bypressing in the stud with the thumbnail.

Among the advantages incident to the specific construction of actuatingdevices as herein shown and described may be mentioned its simplicityand efficiency, its economy and facility of manufacture, requiring butfew and convenient operations for making and fitting the hook-plate andstud in combination; when assembled the stud and spring, being securelyretained in the hookplate, do not drop out of place with liability ofbecoming lost when the revolver is taken apart for cleaning, &c.; itsstrength and durability and precision in operation, as the parallelshoulders give close support to the head of the stud, while it acts by adirect radial reciprocalive movement and is not subject to derangementor breakage either of the stud or its spring. V

I claim as'r'ny invention and desire to secure by Letters Patent- 1. Animproved ejector operator for re Volvers, comprising the radiallyreciprocating stud having a rectangular head, an inclined end face andcylindrical shank with a recess on the side thereof, the hook-platecarrying the ejector-elevating hook, said hook-plate having a radialhole that receives the shank of said stud, and at its peripheryatransverse rectangular recess with square parallel shoulders thatembrace and support the head of said stud, the coiled spring forprojecting said stud, and the retaining pin arranged in the plate, asset forth.

2. In an ejector mechanism for revolving fire arms, the hook-platehavingthe rectangular transverse recess and inwardly extending holetherein, the square-headed stud arranged in said recess with its shankinserted in said hole, the outer end of said stud having an outwardlyinclined or curved surface and an engaging edge, the coiled springdisposed within said hole for exerting outward pressure on said stud,and the retaining-pin passing through the hook-plate and engagingin arecess in the side of the stud; in combination with the ejector, theframe having the foreend shoulder and the barrel having the hinge, asset forth.
